Title: Halftone generator
Inventor: HAINS CHARLES M
IPC: G06T5/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To generate tint dots through the combination of two threshold array and a small look-up table to generate halftone dots that are not grow monotonously. SOLUTION: A memory 52 stores values for two threshold arrays. A digital input from a generator 54 that provides an output of a desired toner converage or a function of a density of a current pixel is applied to a look-up table 51, where which of the two arrays is to be used is discriminated and from which an address bit is outputted to the memory 52. A current pixel address in the memory 52 is given to the memory 52 as a remainder address of addressing by a Holady's address generator 55, and output from the memory 52 is a digital threshold level, which is given to a comparator 53, where it is compared with the image input and from which '1' or '0' bit is outputted.

IPC: B29B7/22
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce the wear of a latch and a drop door to make a wear member have long life and to miniaturize a latch device and to surely perform clamp actuation by interposing between a latch and a drop door an intermediate member freely slidable in the inclined direction of the inclined surfaces of the latch and the drop door. SOLUTION: In a latch device 9 in a closed kneader, a lubricating shuttle member 20 (intermediate part) is supported so as to make it freely slidable by an inclined surface 11a of a latch 11 of the latch device 9, and the shuttle member 20 is interposed between the latch 11 and a drop door 2 during clamp actuation. And at the beginning of clamp actuation of the drop door 2 by the latch 11, first the intermediate member 20 is pressed against the inclined surface of the drop door 2 to generate large static friction between them, and while static friction between the inclined surface of the latch 11 and the intermediate member 20 is reduced by it, only the latch 11 is slid and pressed against the drop door 2 side to perform clamping. Therefore, friction between the latch 11 and the drop door 2 is reduced.

Abstract: PURPOSE:To shorten time for transferring the electric charge of a four-phase driving system register by generating difference in a potential between driving parts when a driving pulse at the same level is impressed. CONSTITUTION:The electric charge transfer device equipped with the register in the four-phase driving system to transfer one bit of the electric charge by four transfer parts is made objective. In this case, when the driving pulse at the same level is impressed, the difference is generated in the potential between and 1st and 3rd transfer parts and the 2nd and 4th transfer parts, for example, when the driving pulse is impressed to the 1st and 2nd transfer parts, the electric charge is transferred from the 1st transfer part to the 2nd transfer part and stored. Afterwards, driving pulses phi1-phi4 are impressed so that the 1st and 2nd transfer parts can be turned to a high level in a 1st transfer block T1, the 3rd transfer part can be turned to the high level in a 2nd transfer block T3, the 3rd and 4th transfer parts can be turned to the high level in a 3rd transfer block T3 and the 1st transfer part can be turned to the high level in a 4th transfer block. Thus, when rate-determining time of transfer is defined as gamma, one cycle of a clock pulse becomes 4gamma, the double data rate as high as conventional one can be obtained, and acceleration is enabled.
